how to set property "java.util.Arrays.useLegacyMergeSort" in jnlp-file?

Hi,

I have a problem in a web start application with java 7 and the new sort behavior (exception: comparison method violates its general contract).

So I like to go back to previous behavior and tried to put the new java 7 system property "java.util.Arrays.useLegacyMergeSort" in the generated jnlp-File:
<property name="java.util.Arrays.useLegacyMergeSort" value="true"/>.

Now I can read the property value in java code with System.getProperty("java.util.Arrays.useLegacyMergeSort"), and guess the property was successful set, but the exception still appears?!

The system property works with command line "javaws -J-Djava.util.Arrays.useLegacyMergeSort=true file.jnlp", but not via doubleclick on the jnlp-file or url and browser.

Any ideas?

Cheers,
Dan
